Hillary Clinton's daughter Chelsea has introduced her mother's formal acceptance of the Democratic presidential nomination with a pledge that as president, Mrs Clinton will fight against gun violence and climate change.

Speaking on the final night of the Democratic National Convention, she said: "I'm here as a proud American, a proud Democrat, a proud mother, and tonight in particular, a very, very proud daughter."

This November, I'm voting for the progressive who will protect our planet from climate and our communities from gun violence.

Who will reform our criminal justice system and who knows that women's rights are human rights, and who knows LGBT rights are human rights - here at home and around the world.

– Chelsea Clinton

In a thinly-veiled swipe at Republican presidential hopeful Donald Trump, she added: "I loved that my parents expected me to have opinions and to be able to back them up with facts."
